javascript - 想要将 $http 方法的响应分配给 angularjs 中的 javascript 变量

Question

我试图将从后端获得的存储在响应对象中的整个数据分配给一个javascript变量，最后主函数$scope.SelectedTerms应该返回该变量。但我得到的是变量数据我正在存储的响应未定义我正在使用 anjularjs

$scope.SelectedTerms = function (feeHeadId,feeHead){
    var data="";
    var datatosend="";
    var formData = {
            customerId : $scope.customerId,
            feeHeadId : feeHeadId,
            selectedOptions : feeHead.feeHeadSelectedOption.display.split("+"),
            payterms : feeHead.pmntTerms
    }

        $http({

        url : '<%= fileReader.getValue("ICOLLECT_SERVICE") %>?<%=ICollectConstants.FLOW_NAME_PARAM%>=<%= ICollectConstants.FLOW_NAME %>&<%=ICollectConstants.MERC_ID%>=<%= icMerchantMasterBean.getIcMerchantMasterId() %>&<%= ICollectConstants.BANK_ID%>=<%= icMerchantMasterBean.getIcBankMasterId()%>&req_id=validateFeeAndSendResponse&checksum=BFEDE97EF99CCF9C1362EBFE7C94E3233ED6E2B7637AC7BDB34AC916D9BAC3AD&reqtoken=<%=req_token%>'+'&method=TEST' ,
        method : "POST",
        params : {
            jsondataforST:btoa(angular.toJson(formData)),
            responseType:"1",
            backUrl :'<%= backUrl%>',
            icMerchantMasterId : <%= icMerchantMasterBean.getIcMerchantMasterId()%>,
            icMerchantBankId : <%= icMerchantMasterBean.getIcBankMasterId()%>
            }
    }).then(function Success(response){
        if(response.data.statusCode=="100"){
            data = response.data;
            //datatosend;
                /*function funccarringSubfee(){
                var value = data[feeHeadId];
                console.log("value inside subFunction");
                console.log(value);
                return value;

            }*/
            //$scope.separateTermLogic(feeHead,data);
        }
    }, function error(response){
        console.log("error occured");
    });

    return data;    //it returns undefinied

};

嘿伙计们，这些对我有用...谢谢您的回复...我刚刚注入(inject)了 $d

   $scope.SelectedTerms = function (feeHeadId,feeHead){
    console.log(" async SelectedTerm function Started");
    var data="";
    var datatosend="";
    var formData = {
            customerId : $scope.customerId,
            feeHeadId : feeHeadId,
            selectedOptions : feeHead.feeHeadSelectedOption.display.split("+"),
            payterms : feeHead.pmntTerms
    }
    var deferred = $q.defer();//newely added
        $http({

        url : '<%= fileReader.getValue("ICOLLECT_SERVICE") %>?<%=ICollectConstants.FLOW_NAME_PARAM%>=<%= ICollectConstants.FLOW_NAME %>&<%=ICollectConstants.MERC_ID%>=<%= icMerchantMasterBean.getIcMerchantMasterId() %>&<%= ICollectConstants.BANK_ID%>=<%= icMerchantMasterBean.getIcBankMasterId()%>&req_id=validateFeeAndSendResponse&checksum=BFEDE97EF99CCF9C1362EBFE7C94E3233ED6E2B7637AC7BDB34AC916D9BAC3AD&reqtoken=<%=req_token%>'+'&method=TEST' ,
        method : "POST",
        params : {
            jsondataforST:btoa(angular.toJson(formData)),
            responseType:"1",
            backUrl :'<%= backUrl%>',
            icMerchantMasterId : <%= icMerchantMasterBean.getIcMerchantMasterId()%>,
            icMerchantBankId : <%= icMerchantMasterBean.getIcBankMasterId()%>
            }
    }).then(function Success(response){
        if(response.data.statusCode=="100"){
            data = response.data;
            console.log("async SelectedTerms:"+feeHeadId+":"+feeHead+":"+data);
            feesforUniquekey = processSelectedTermsResponse(feeHeadId,feeHead,data);
            deferred.resolve(feesforUniquekey);// These Resolve() sends the data .
        }
    }, function error(response){
        console.log("async error occured");
        deferred.reject({ message: "Really bad" });
    });

    //return data;  
    console.log(" async Selected term function End");
    return deferred.promise;
};
